My Pro Tools System started crashing on launch a couple weeks ago, and finally wouldn't open altogether. I have backed up my hard drive, reinstalled the OS X to it original when I bought it, 10.4.5, and then reinstalled Pro Tools 7.0. For some reason the Mac (mini) is having trouble "talking" to the M Box2. None of the lights flash up and if I go into the Audio/Midi set up in Utilities, it does not recognize the M Box2 so it's obviously not being read. I think that somehow the CoreAudio Driver is not being installed properly when I install Pro tools, but I'm not sure. I do desperately need some help as I have some major job deadlines!! Thanks!!!!!
